The Alt Code shortcut for the A Umlaut Symbol is Alt + 0228 for lowercase and Alt + 0196 for uppercase.
foo.txt), dots in pairs are usually seen alone.where they have special meaning: the parent directory of the current directory (.
TL DR Your proposed schemes are safe if you avoid names that begin with dash.Īdditional word of caution: Though dots by themselves are common, especially to separate a file's base name from its "extension" (e.g. then don't be surprised to see something like Unknown option '-my-dash-first-file'. For example, if a script passes the filename to another script like this: some-script -my-dash-first-file. This is legal, of course, but there are too many programs in existence that will handle such names improperly resulting in them being interpreted as command-line options/flags. (Of course, right?) I don't see any indication that you plan on doing this but it should be noted: avoid dashes at the beginning of a name. Common tools, languages and regular expressions will handle them fine. (Spaces and newlines are two of the most troublesome.) In fact, dots and dashes are very widely used. However, they tend to barf on a very particular set of characters and those characters are not dots or dashes. POSIX-compliant and/or well written programs and scripts will handle such lenience but, unfortunately, there are countless examples out there that don't. One of the more scrutinized and second-guessed design decisions in Unix/Linux is a file system feature that is working in your favor: any character is allowed in a file/directory name except for NUL \0 (ASCII 000) and slash / (the latter being reserved for file paths). However, I'm not certain, especially regarding how regular expressions or python scripts can handle these files and folders (I have very little experience with both, but I'm learning).ĭisregarding the behavior of specialized software, would you say these delimiters are generally safe for common file systems and scripting languages? are totally acceptable, and I'm thinking of finally choosing. Should file names contain multiple periods?.Is it bad practice for folder name to contain dot (.)? How about file name with multiple dots?.Are periods (“.”) valid characters in file or folder names?., which is already primarily reserved for the numerical values with a decimal point.Īccording to several posts across SE network, e.g. I haven't included comma, (as it has been rightfully suggested in the comments, this is also a viable character to consider) as I think it's easy to confuse it with a single dot.Visually I find it's hard to quickly tell the difference between _ and _, whereas - vs - and.However, this is 3 characters and the filenames are already pretty lengthy (as one can tell from the examples), so I'd like to stick with two characters if possible. Among their combinations the most popular, it seems, is _-_.
